Menopause Hormone Therapy (HRT) in Redwood City, CA

Bioidentical hormones in Redwood City: what it means

"Bioidentical" is a word compounding pharmacies often use in marketing, but what it describes is real: a hormone built like the body's own. Estradiol and micronized progesterone are both bioidentical: their structure matches the hormones the ovaries make. Both come in FDA-approved prescription forms, from estradiol pills, patches, gels and vaginal forms to progesterone capsules.

"BHRT" often means compounded hormones, a cream, a blend such as Bi-Est or a pellet that a pharmacy mixes for one prescription. Compounded drugs are not FDA-approved, so the FDA cannot assure their safety, effectiveness or dose. The FDA says it has no evidence that compounded "bioidentical hormones" are safe and effective, or more effective than FDA-approved hormone therapy. When the National Academies reviewed them in 2020, the evidence was mostly low quality, such as anecdotes and patient reports.

34 OB-GYNs in the federal NPI registry give a primary practice address in Redwood City: 41.3 per 100,000 residents, above the US rate of 17.8 and above California's 16.9, and more per resident than 80% of the 924 cities VevaMD covers. Set against the city's 10,356 women aged 45 to 64, that is one OB-GYN for roughly every 300.

Within 25 miles of Redwood City there are 1,266 OB-GYNs for 4,521,732 residents (28.0 per 100,000), well above the national rate; 302 are in the city or within 10 miles. Whether or not you have an OB-GYN, you can ask a physician licensed in California about menopause hormone therapy online from Redwood City, with no waiting room.

You do not choose a "bioidentical" product from a menu: after a private intake, a physician licensed in California decides what, if anything, fits, and the form. Pellets are not part of it. Since the pharmacy that fills these prescriptions also compounds, ask whether yours is an FDA-approved product or compounded. Testosterone cream for women and Bi-Est are compounded and not FDA-approved.

A pellet clinic is a different model: it implants a hormone pellet under the skin during a visit, and compounded pellets are not FDA-approved. The Endocrine Society cites blood levels well above the expected range in women using compounded pellets. ACOG's guidance is to prefer FDA-approved menopause hormone therapy to compounded hormones.
